Title: Dynamic friction factor measuring apparatus
Inventor: MIYAGAWA HIDEAKI
IPC: G01N19/02
Filed: 1987-03-24
Abstract: PURPOSE:To measure a dynamic friction factor accurately under conditions close to those in an actual tape running system, by making a tape on a rotary drum slide in contact with a dynamic friction factor measuring mechanism having a magnetic head or the like to detect horizontal and vertical pressure components. CONSTITUTION:A tape is wound on the circumference of a rotary drum 11 and rotated with a motor 13. A dynamic friction coefficient measuring mechanism 15 is provided as opposed to the tape. The measuring mechanism 15 is made up of a permanent magnet 18 and a magnetic head 19 mounted on a plate spring 17 and additionally, a magnetic sensor 21 mounted on a support plate 20. Then, the tape is turned to be kept sliding in contact with the magnetic head 19. Here, a horizontal pressure component F receiving by the magnetic head 19 is detected with a pressure detector section 24. A vertical pressure component W is detected with the permanent magnet 18 and the magnetic sensor 21. In this manner, a dynamic friction factor mu(=horizontal pressure component F/vertical pressure component W) is determined. Thus, the horizontal and vertical pressure components of the magnetic head are detected thereby enabling accurate measurement of a dynamic friction factor under the conditions the same as those in a type running state of an actual VTR running system.

Filed: 1994-04-08
Abstract: PURPOSE:To simplify an adjusting mechanism and enhance the value added by setting up the taper direction of a sector gear so that a pitman shaft may receive component force in a specified axial direction. CONSTITUTION:A stopper member which can abut on a pitman shaft 18 is provided in the axial center direction of the pitman shaft 18, and the taper direction of a sector gear 18G is set up so that component force by which the pitman shaft 18 is pressed against a stopper member 25 with the push- drawing operation of a push-drawing member 19 may be caused. Thus, since even if the push-drawing member 19 is operated in either direction of pushing or drawing, the pitman shaft 18 receives the component force in a specified axial direction, positioning function is preferable to exist in the direction of the component force. Thus, only positioning to one of axial directions of the pitman shaft 18 is enough for an adjusting mechanism, and namely it is sufficient for the above mechanism to only threadedly attach an adjusting screw 25 to the tail cover 26 of a steering casing 17 with a lock nut 27, and the simplification of an adjusting mechanism B therefore becomes possible.

Title: Push-button channel selector
Inventor: NOJI TASUKU
IPC: H03J5/32
Filed: 1980-05-28
Abstract: PURPOSE:To prevent illegal reception of an end user by coupling a channel-selection switch with a pay switch through the operation of one push button. CONSTITUTION:When pay channel reception is unnecessary, even if a corresponding push bottom 11 for channel selection is pushed, a finger Fi never touches a fixed contact 23ai because the bending angle of a moving contact to a matrix substrate 23 of each finger Fi is made small, so that a distrubance signal is mixed into an RF signal. For the pay channel reception, on the other hand, only a finger Fi (1) for a prescribed channel is bent nearly at right angles, and consequently the depression of the push bottom for channel selection forms a short circuit between the finger Fi (1) of the moving contact 22ai and the fixed contact 23ai, thereby preventing the mixing of the disturbance signal.

Filed: 1992-03-27
Abstract: PURPOSE:To provide the acoustic reproduction device preventing deterioration in the S/N and increase in power consumption when left and right surround speakers output 2-channel surround signals from an audio signal sent in the radio system. CONSTITUTION:Audio signals L, R from a video tape recorder 1 are converted into a difference signal (L-R) by a radio transmitter 7 and also into a monaural radio signal M(L-R) and the result is sent to a radio receiver 8 as a radio wave.

Thus, while the deterioration in the S/N and increase in power consumption is prevented in the case of transmission by the radio system, two channel surround signals are outputted to the left/right surround speakers arranged at the back side of the listener.
